An administrator needs to administer a broker on a Windows platform through the Administration API exerciser. How can the administrator start the exerciser?
Run the shell script install_dir\sample\ConfigManagerProxy\StartConfigManagerProxyExerciser from a WebSphere Message Broker Command Console.
An administrator needs to update an existing Problem Management Record (PMR) with specific technical information. How can the administrator perform this activity in the least amount of steps?
Log into the Electronic Service Request (ESR/SR) tool and update the PMR.
An administrator needs to configure multi-instance WebSphere Broker environments that allow for the continued processing of already existing and new incoming messages at the messaging layer. What are the tasks required to configure a multi-instance broker on WebSphere Message Broker? Two network servers are to:
be configured to host shared work paths for the multi-instance broker and shared directories for the multi-instance queue manager (Active/Passive).
An administrator has backed up the broker using the command mqsibackupbroker. The command was issued while the broker was running and processing deployments. What is the outcome?
The backup file contains incomplete information and is unusable.
A multi-instance broker has been created on nodes A and B. To verify the multi-instance broker, an administrator starts the broker on node A and then on node B, and then runs the command mqsilist. What state of the broker will be displayed if the multi-instance broker is running successfully? The broker is running:
in active mode on node A and in standby mode on node B.
An administrator is asked to write an Administration API (CMP API) based application for monitoring the message broker environment. What are prerequisites to run Java applications that use the CMP API?

A message flow that includes HTTP nodes is deployed to 3 execution groups in a broker. All HTTP nodes are configured to use a single port. After performance testing, it is decided that the inbound and outbound HTTP messages in each execution group should be routed through separate listener ports in order to achieve higher throughput. An administrator is asked to make the configuration changes. Which one of the following actions is required to achieve this?
Run command mqsichangeproperties to disable the broker-wide listener.
An administrator is required to configure the Public Key Infrastructure at the broker level. This will allow use of HTTPS request calls to web services. Which commands will set the keystore and truststore properties?

A message flow Flow1 is running on execution group EG1 on the broker BRK1. As per the business requirement, the flow accesses the database for transformation and routing. The user ID and password used by the flow need to be changed to adhere to the company's new policy for user IDs and passwords. The administrator has been asked to change the user ID and password for the given message flow without affecting other flows. The administrator is using the mqsisetdbparms command to set the user ID and password. Which command should the administrator use next?
mqsireload BRK1 -e EG1
The broker environment in a company is as follows: The administrator has set up Public Key Infrastructure (PKI) at the broker level. For the flows that contained SOAP Input nodes, the administrator has set up PKI at the execution group level. The administrator also configured the broker-wide listener for the HTTP node based web services. In this environment, the administrator was asked to deploy a new secured web service based on HTTP nodes in the same execution group that contained SOAP node based web service. After a few days the partner system that was making HTTP(s) calls to this new web service reported SSL certificate expiry errors. What should the administrator do to resolve this problem?
Update the certificate at the broker level PKI.
An administrator was asked to give security permissions to an Administration API based application that displays the execution groups and associated message flows. Which of the following security access levels should the administrator set for the application's user ID?

On a detailed analysis, the administrator notices that a new flow has been deployed in the execution group that has around 20 nodes but a lot of them are user defined nodes. What action should the administrator take to resolve this problem?
Increase the JVM heap size of the execution group.
A company has a business scenario whereby a request on their application has to pass through various vendors to generate a response. Each vendor invocation results in a message response which comes in different formats (SWIFT, XML, SEPA). The final response to the initial request has to be sent in EDIFACT format to the end client. What is the recommended way for implementation?
Implement transformation and aggregation of the vendors' responses in WebSphere Message Broker.

A WebSphere Message Broker V6 has been used in a financial company on an AIX system in production environment for years. The broker is configured with a high availability solution. The components in the resource group include both the broker and a client application database. The company plans to create a new WebSphere Message Broker V7 environment and migrate the existing broker to the V7 system with the same business requirements. An administrator is asked to review and provide a design proposal for the high availability and failover in the WebSphere Message Broker V7 system. Which of the following options should the administrator recommend?
Use a multi-instance broker to replace the current high availability solution.

A company has a central server, which stores the catalogue price of everything that the company sells. This information is required by all Point of Sale (PoS) terminals in all the stores, and each PoS terminal must be notified of any price change. The PoS terminals connect to the central server through TCP/IP and wait for any price changes. The server sends any price changes to all connected client applications.

How can the administrator verify which of the user-defined extensions have been loaded by the broker?
A company is planning to evaluate WebSphere Message Broker as an ESB across its various departments. The administrator is asked to set up a new broker environment for this purpose with the condition that one department does not have any access to other department's resources. Which of the following options should the administrator implement that will involve the least administrative overhead?
Create one execution group for each department and use the broker administration security to restrict access.
